This study focuses on science, technology, engineering and mathematics (STEM) education teachers’ perspectives on integrating indigenous knowledge systems (IKS) into a multidisciplinary STEM framework to promote sustainability. The aim is to understand how integrating the values, ethics and worldviews of the global community can contribute to a sustainable mindset. Through an examination of the research background and pedagogical foundations, as well as a review of existing literature, it becomes evident that teachers’ perspectives are pivotal in fostering a sustainable mindset among students. To encourage social dialogue that has the potential to evolve teachers’ perspectives, a 6 month workshop focused on dialogic argumentation was provided to a group of basic education and university STEM teachers. The workshop aimed to explore the evidence- and reasoning-based arguments that influenced their perspectives regarding the role of IKS in STEM education. Analysis of data collected through questionnaires and interviews yielded the following findings: (a) initially, most teachers had mixed feelings about the role of IKS in STEM education for sustainable development; (b) a significant number of teachers reported that the dialogic argumentation workshop helped them transition from a negative to a positive attitude towards acknowledging the complexity of the role of IKS in promoting various approaches to achieving sustainability goals; and (c) several others, particularly university teachers, attributed IKS with the potential to enhance reflective reasoning in order to solve complex sustainability problems. The implications of these findings for classroom practice, particularly in terms of utilising IKS to enhance STEM teacher education, are highlighted in the paper. [ABSTRACT FROM AUTHOR]

Among the problems identified at Technical and Vocational Education and Training (TVET) colleges, low achievement in mathematical subjects is the most prominent one. This paper documents a qualitative case study undertaken at TVET College in Gauteng with the purpose of exploring the National Certificate Vocational (NC(V)) Level 4 students' errors and associated misconceptions when answering optimisation questions in differential calculus. The participants were 60 students who were registered for a course in mathematics. Data were generated from the written student responses to two non-routine test items followed by interviews. Using the Newman error hierarchical model to analyse the data, it was discovered that students errors were conceptual and procedural as well as systematic and non-systematic. The literature also alluded to instructional approaches as some of the causes of students' misconceptions and the errors and that interventions should target students as well as the instructors.
